asme boiler water treatment guidelines

Chemical plant asme boiler water treatment guidelines tube rupture occurs comprehensive analysis: chemical plant boiler tube rupture occurs comprehensive analysis of the chemical plant boiler tube rupture occurs a comprehensive analysis of 1, the degree of harm mainly chemical plant boiler explosion occurs tube boiler pipe explosion refers to the smoke tube, water wall tube and damage to the convection tubes. Boiler tubes, steam, irrigated violation, boiler water shortage caused by a short time, if not handled properly, will continue to expand, a serious threat to the safe production and use of living units. 2, squib Analysis (1) poor circulation caused by blockage boiler tubes, resulting in localized overheating of the boiler and the chemical squib occur. Common cause clogging pipes are: water treatment failed, boiler tubes pollution, a new tube through ball without inspection, there is sand and other debris inside the tube or bring yarn, and other debris off the scale. (2) tube local damage, such as a touch or mechanical damage reaches a local recess, resulting in damage to local wear blowing baffle wall (wall off smoke) partial tube is short-circuited, fly close to the furnace wall tube wear flue-speed localized corrosion and thinning the flow tube, and the like. (3) Pipe manufacturing defects, such as poor quality welding, the structure is irrational, inextensible tubes and the like. Local temperature changes (4) of the pipe is large, resulting in cracking of the pipe, as will water improperly treated, fire, water temperature is low, into the boiler with the boiler water and poor mixing. (5) Slagging not promptly removed, fresh water after improper handling, improper firing uneven heating of the tube, a low water temperature, the mixing pot into the boiler water is not good. (5) Slagging not removed, resulting in uneven heating, water circulation damage. 3, chemical treatment of boiler occurs squib (1) reduce the load to stop blowing, increased water supply, the water level is maintained, and immediately reported to the leader according to the normal shutdown process. (2) water level gauge can not keep the water level, when the water level unseen, should immediately stop the water, emergency stop hearth, but should continue to operate, so that the smoke and steam discharged from the furnace.

How to improve the thermal efficiency of gas-fired asme boiler water treatment guidelines fuel: fuel gas for the boiler, in order to save fuel, improve the thermal efficiency of the boiler, common measures are: 1, the use of flue gas heat recovery technology to reduce exhaust losses. The main factors influencing the heat loss is the exhaust gas temperature. The higher the exhaust gas temperature, the greater heat losses. Currently, when most of the new boiler factory is equipped with flue gas heat recovery unit, such as economizers, half or full condensation condensing flue gas heat recovery device, these measures can effectively reduce exhaust gas temperature and improve the thermal efficiency of the boiler. 2, when the excess air coefficient is too high, excess equivalent of inhaled cold air into the furnace, which is not involved in some of the excess cold air combustion, but is freely drained after heating increases heat losses; as entering the furnace cold air continues to increase, beyond a certain limit, the furnace temperature will be reduced, can also cause incomplete combustion loss increases. When the excess air coefficient is too low, the fuel can not get enough oxygen for complete combustion, resulting in incomplete combustion loss increases. The long-term severe incomplete combustion, boiler heating surface will result in carbon impact heat transfer efficiency, continues to increase exhaust losses. Therefore, the reasonable control of the air-fuel ratio to minimize heat losses and incomplete combustion losses q2 q3, is another key point to enhance the thermal efficiency of the boiler. 3, strict control of boiler water quality, scientific management and control scale. Boiler feed water will contain various impurities and calcium and magnesium scale substances, boiler fouling inevitably. Low thermal conductivity of the scale, so that once the heating surface increases the thermal resistance to fouling, boiler exhaust gas temperature rises, heat losses will increase. Test data indicate that the boiler heating surface junction 1mm scale, heat losses will increase from about 2% to 4%, the thicker the scale boiler heating surface, the greater the resistance, the thermal efficiency of the boiler will be lowered more. Boiler fouling not only reduces the thermal efficiency of the boiler, and the boiler Heating Surface temperature rise, causing heating surface damage, and even cause boiler explosion. Therefore, high-quality soft water treatment apparatus, in strict accordance with the process operating boiler feed water softening apparatus, boiler feed water quality control, can delay scale formation. Meanwhile, boiler scale control in real time to master the situation boiler scale, a scale clean-up, if necessary, is also very important. 4, strengthen the insulation, to prevent leaking, reduce heat loss.

The water temperature control range of the hot water asme boiler water treatment guidelines can be controlled within 5 degrees from now on to improve the working efficiency and use effect of the hot water boiler. This kind of boiler, if it is chemically treated outside the pot, has a requirement on the total hardness of the feed water. Generally, the total hardness of the feed water is required to be no more than 0.6 mmol/L, and it is not sloppy to strictly enforce this requirement.

Around the low nitrogen emissions and thermal efficiency of the asme boiler water treatment guidelines regard, Jiang Zuojun, who are very interested in the company's showroom will watch the animated presentation, could not help nodding in approval, other fast boiler in a variety of achievements in the industry made a lot of money and gave high praise and affirmation. Subsequently, a pedestrian visited the lab to clean the boiler group, for the constitution and the implementation of the Group's research laboratory work was questioned and understanding.

Water Hardness is the primary source of scale in boiler equipment. Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica.
